Answer:

x = 61.5

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Sum the 4 angles and equate to 360

110 + 130 + x + x - 3 = 360

2x + 237 = 360 ( subtract 237 from both sides )

2x = 123 ( divide both sides by 2 )

x = 61.5

Answer: Sample space for:

Coin (S) ={H, T}

Spinner (S) = {Green, Red, Orange, Purple, Yellow}

All the Possible outcome for:

Coin =1

Spinner = 1

The total outcome there = 7

Probability of flipping tails and not spinning purple or green

=11/10

Step-by-step explanation:

All the Possible outcome for:

Coin =1/2+1/2=1

Spinner = 1/5+1/5+1/5+1/5+1/5=1

The probability of flipping tails. = 1/2

The probability of not spinning purple or green = 3/5

Therefore, the probability of flipping tails and not spinning purple or green

= 1/2+3/5

=11/10

Answer:

$221

Step-by-step explanation:

Hello!

The total cost s $627.83, for one desk that costs $185.83, and two identical chairs (c).

The equation: $185.83 + 2c = $627.83

This equation represents the cost of the desk plus two chairs of the same price, which adds up to the total price.

Solve for c:

  • $185.83 + 2c = $627.83
  • 2c = $442
  • c = $221

Each chair, c, costs $221.
